Features

Fixed slits for high accuracy and repeatability

The fixed slits slide into the holders at all instrument ports, with the exception of those ports configured to mount a camera. The slit holders are installed by Newport during calibration of the instrument. The width and height cannot be adjusted, but may be individually replaced with other slit sizes. Fixed slits are a low cost alternative with excellent repeatability. They are a good choice when only a few slit sizes are required. They are sold separately to allow customized choices based on the needs of the application. When ordering, be sure to purchase fixed slits of the same model (i.e. same size) for the input port and output port(s). Oriel offers fixed slits in widths from 10 µm to 5.0 mm. Each of the fixed slits is mounted in a precision machined slide which is inserted into the 77294 or 77721 fixed slit holder. Contact Newport Sales for more information.

Micrometer adjustable slits for flexibility and high throughput

A micrometer adjustable slit assembly is continuously variable from fully closed to 3 mm width. The narrowest practically achievable width is 4 µm. A height adjustment slide allows variation in the height from 2 to 12 mm. Benefits of the micrometer adjustable slits are flexibility and high throughput. Please note that optimum spectral resolution for any monochromator is obtained with short, narrow slits. This type of slit is designed primarily for versatility and convenience in changing resolution and throughput; fixed slits should be used for the utmost accuracy and repeatability, especially at high resolution.

Motorized slits for computer control, automatic bandwidth selection

Two motor driven slit assemblies are offered for the MS257. A motorized slit assembly may be adjusted from 6 µm to 2 mm width in 6 µm steps. The slit width is controlled through the utility software, optional hand controller, optional TracQ Basic software or by using low level commands. An advantage of using motorized slits is that in addition to setting the slit widths individually, the software can be configured to an automatic bandpass setting. The software adjusts the slit widths to maintain the chosen bandpass as scans are performed using multiple gratings and either output port. Factory recalibration service is recommended when transitioning to a motorized slit assembly.
